AMBRATMen's Adult Black Star Themed S.T.A.R. Labs Hoody Top - Long Sleeve Hoodie

are these child sizes or could fit a 6ft teen a little broad, if so what size?

If I'm 5'4 and about 132 lbs (girl), should I get a small or medium? Don't want it to be too baggy.

Are these child sizes as a xxl states 26inch chest ?

I’m 5’2 and 41kg(I'm kinda tiny for a girl) but I want this to be an oversized hoodie. Should I get small or medium then?
